can someone please help me get() got an unexpected keyword argument 'pk' in that error

Answer 1

The error is quite explicit. The get method is missing an argument.
In order to fix that:
class PostLikeApiToggle(APIView):
...
def get(self, request, pk, format=None):
Why did you get that error ?
Your urls.py defines the path as 'blog/<int:pk>/like/'. Django will resolve that url and call the view's method - get in your case - with the group names/values as keyword arguments - refer to the point 4 of the documentation for more details about how Django processes requests.
